Historical Unidata Internet Data Distribution (IDD) Gridded Model
Data are obtained via the Unidata Internet Data Distribution System
(IDD). Data includes gridded analyses and forecasts from US National
Centers for Environmental Prediction (NCEP) and European Centre for
Medium-Range Weather Forecasts (ECMWF) models. Models include NCEP
ETA, NAM and RUC covering the Continental US, NCEP Ensemble and GFS
covering North America and the globe, and GFS Extended and ECMWF
covering the globe, at various spatial and temporal resolutions.
Potential variables found in the model output include pressure,
relative humidity, temperature, geopotential height, zonal component
wind speed, and V-component wind speed.
Online archives include 1 year of data, and are populated daily with
model output generated two days prior to the current date.
Additionally, GFS Global 0.5 degree analysis fields from November
2006 to near the present are available online for web download.
Older historical files, beginning in December 2002, are available
upon request.
